Prenatal Corticosteroids and Antioxidants in Preterm Infants - Full Text View

ClinicalTrials.gov Identifier:	NCT00791687

Purpose

Premature infants are highly susceptible to oxidative stress because of the immaturity of their antioxidant defense system. The use of prenatal glucocorticosteroids administered to the mother improves respiratory function and overall outcome. The investigators hypothesize that prenatal glucocorticosteroids favor the expression and competence of the antioxidant defense system.

Groups/Cohorts
PRENATAL CORTICOSTEROIDS Extremely low gestational age neonates (<28 weeks gestation) whose mothers received full course of betamethasone before delivery.
NON PRENATAL CORTICOSTEROIDS Extremely low gestational age neonates (<28 weeks gestation) whose mothers did not receive full course of betamethasone before delivery.

Detailed Description:

This is an observational study recruiting extremely low gestational age neonates (<28 weeks gestation) whose mothers received or not full scheduled prenatal glucocorticosteroids. Healthy term newly born infants acted as controls.

At birth cord blood were drawn for the following analytical determinations: reduced and oxidized glutathione; malondialdehyde; superoxide dismutase; catalase; glutathione peroxidase; glutathione reductase; glutathione s-transferase. In addition, first urine voided was collected for ortho-tyrosine/phenylalanine and 8-hydroxy-2-oxo-deoxyguanosine/2-deoxyguanosine determination. Analytical data and clinical outcomes are compared.
